How is Spags not a Head Coach?

How has Steve Spagnuolo not gotten another shot at a head coaching gig? And to my memory why haven’t the Giants interviewed him when we had a HC vacancy?

I know his stint as HC with the Rams was not great (10-38 record) but his QBs were Marc Bulger a season before he retired and Sam Bradford…..in the time since his KC defense has won 4 SBs and are playing in their 6th. For all of the love Mahommes gets, the KC defense has been the better unit for several years.

According to NBC Sports he interviewed this past January for HC for the Jets, Jaguars and Raiders. So I don’t blame him for turning those offers down to continue winning in KC but how is this guy not a HC after 5 maybe 6 SBs?

Did the Giants interviewed him after firing Joe Judge? And if not what am I missing?
